The Portuguese Newborn Screening Program currently includes 28 pathologies: congenital hypothyroidism, cystic fibrosis, 24 inborn errors of metabolism, sickle cell disease and spinal muscular atrophy. This pilot study for sickle cell disease newborn screening, including 188,217 samples, was performed between May 2021 and December 2023, with phase I, including 24,130 newborns, in the Lisbon and Setubal districts...

With the popularity of smartphones and mobile devices, mobile application (a.k.a. “app”) markets have been growing exponentially in terms of the number of users and downloads. To increase user satisfaction, app developers invest a lot of work into gathering and utilizing user input. This paper presents an analysis of the mobile app market through the development of a mobile app. The app provides users with an o...
ABSTRACT: The Calcium-looping process is a promising option for thermochemical energy storage in concentrating solar power plants. A crucial element of this process is the solar calcination reactor, where the endothermic reaction of CaCO3 calcination occurs with formation of CaO and CO2. The solar energy that is chemically stored in the reaction products can be retrieved by the exothermic reaction of CaO carbon...
ABSTRACT: The calcium looping process, based on the reversible calcination-carbonation reaction cycle of CaCO3-CaO, is an emerging and promising technology for thermochemical energy storage in concentrating solar power plants. In this process, concentrated solar energy is used to carry out the endothermic solar-driven calcination of CaCO3 with formation of CaO and CO2 as products in a solid-gas reactor. In this...
Big Data introduces a significant increase of complexity to projects, in which, the use of inadequate data will inevitably produce inadequate and incorrect analysis. Data Catalogs centralize the system’s metadata into one place, providing a global view of the stored data, so it is essential to use appropriate data catalog tools. The choice of the tool that best suits the needs of the projects must be well-found...
As hemoglobinopatias são as doenças hereditárias mais frequentes a nível mundial e que resultam de mutações que afetam os genes responsáveis pela síntese das cadeias de globina da hemoglobina. Trata-se de uma patologia cada vez mais disseminada à escala global, e consequentemente, é cada vez maior a importância do rastreio neonatal da drepanocitose para a diminuição da morbilidade e mortalidade através de adoçã...

Este trabalho teve por objetivo a avaliação do impacto da hiperoxigenação do mosto da casta Fernão Pires no perfil aromático do vinho obtido. Após a prensagem, o mosto foi hiperoxigenado, durante 6 horas, com o auxílio de um micro-oxigenador Vivelys, com 7 mg/L e 14 mg/L de oxigénio. O mosto controlo apenas foi sulfitado. As fermentações decorreram à temperatura controlada de 15 °C. Após a extração líquido-líqu...
ABSTRACT: A new unidimensional computational model is developed to simulate a calcination reactor in a Calcium-looping process for thermochemical energy storage in concentrating solar power systems. The proposed reactor is an absorber tube exposed to concentrated solar radiation. This tube is also the riser of a circulating fluidised bed where the calcination reaction takes place. The proposed heat transfer pro...
